Case Study: Large Financial Organization achieves confident SAP migration and automated middleware testing with Parasoft

Financial Organization Virtualizes SAP & Seamlessly Migrates Legacy System

A large financial organisation was migrating off legacy systems to SAP and needed to ensure its middleware mapping and transformation logic worked correctly without disrupting customers. Manual, service‑layer testing was too slow and dependent on SAP availability, creating risk during frequent middleware iterations and making it hard to justify testing investment.

To address this they adopted Parasoft’s Continuous Testing platform—using Parasoft Virtualize to simulate SAP and other backends and Parasoft SOAtest to build automated API tests. By virtualising eight backends and integrating event monitoring, the team developed repeatable tests that ran after each middleware build, enabling early development against anticipated backend behavior, faster defect detection, and more reliable releases. The approach eliminated test-data bottlenecks and exceeded their defect‑avoidance ROI target by 68%.
